VEHICLE-SPRING.

SPECIFICATION forming part of Letters Patent No. 336,544, dated February 23, 1886.

Application filed July 8, 1885. Serial No. 170.988.

T0 aZZ whom) it iitay concern:

Be it known that 1, MICHAEL BARRY, a citizen of the United States, residing at Valparaiso, in the county of Porter and State of Indiana, have invented certain new and useful Improvements in Vehicle'Springs; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and to letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to springs for vehicles; and it consists in the detailed construction of the same, as hereinafter fully described and claimed.

This spring made in two separate parts, which are securely bolted or riveted together, thus forming a jointless elliptic spring of great length and flexibility, which permits the body of the vehicle to hang as low as when a side bar is used, and which also prevents pitching and rattling.

I will now proceed to describe theinvention, with reference to the accompanying drawings, in which Figure 1 is a side view of the complete spring. Fig. 2 is a plan View of the same. Fig. 3 is a plan view of one of the halves of the spring before being secured to the other half. Fig. 4 is an end view of the same.

Similarletters of reference, where used in the different figures,indicate coi responding parts.

A A are the two halves of which the spring is formed. These are exactly alike in form, each consisting of aseparate spring bent into the form ofan ellipse and havingits ends turned The lugs caproject at right angles from the spring at the end of each of the loops a a. Each spring A may be strengthened in the usual manner by the (No model.)

addition of the springs B, secured upon the back of it.

The springs A are placed together, as shown in Figs. 1 and 2 of the drawings, and firmly secured by the bolts a a", which pass through holes in the lugs a a.

Instead of bolts, rivets or clips may be used to fasten the ends of the springs together, the object being to unite them securely and with out forming any workingjoint at the ends of the springs, as such joints in time become loose from wear and allow the vehicle-body to pitch about and rattle.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The vehiclespring A,bent to the form of an ellipse, and having the loops a a at each end, and the lugs a a, projecting from the ends of the loops at right angles to the spring, substantially as and for the purpose set forth.

2. In a vehiclespring, the combination of two springs bent to the form of an ellipse,fir1nly secured together without knuckle or working joint by lugs projecting at right angles from the ends of each of them, so that the said springs have their vertical movements opposite to each other and in separate parallel planes, substantially as and for the purpose set forth.

3. In a vehicle-spring, the combination of two springs, A, bent to the form of an ellipse, and having loops a a at each end, and thelugs a a, projecting from the ends of the loops at right angles to the spring, and the bolts a a, for securing the said lugs firmly together, substantially as and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.

MICHAEL BARRY.
